DM commands of the three probe shapes used for the electric field estimation, overlaid on the Roman LS of the HLC configuration of THD2. All are normalized to a unit amplitude of one. The probes are applied on the in-pupil DM2 in all cases. Top: two of the three probes in the sinc-sinc-sine set. The third probe (not shown in this figure) is the same as the top left one but rotated by 90 degrees, located in the same place on the DM. Bottom: one of the single actuators (left) and sharp sinc probes (right). Both are centered on the same actuator. The other two probes of each set (not shown in this figure) are a copy of the two shown here, with a one-actuator offset to the left and to the top.
